Patent DE-2720357-A1 (DE)
Title: Balanced IC engine with opposed pistons - has connection to crank by parallelogram linkage pivoted to pistons at diagonally opposite points
Inventor: ZINK WERNER
IPC: F02B75/18
Filed: 1977-05-06
Abstract: The IC engine has two coaxial cylinders extending radially from opposite sides of a crankshaft axis. Four pivotally connected links forming a parallelogram are pivoted at two diagonally opposite points to the respective pistons. At the other two points of the parallelogram the links are pivoted to the one ends of two connecting rods. The other ends of the connecting rods are pivoted to two diametrally opposite crank pins of the crankshaft. The pistons move in opposite directions, avoiding out of balance forces. Symmetry of the link connection ensures that the pistons are free from side loads.

Title: System for stamping articles moving in parallel streams - has separate arm with stamping mechanism for each stream
Inventor: HAEGERMANN HELMUT
IPC: B44B5/00
Filed: 1977-05-18
Abstract: The stamping of identification symbols on articles which are travelling on a conveyor in parallel streams is achieved by a row of swinging arms. There is one arm (1) for each row and each arm is suspended from a common tube (2) which houses the air supply pipes (8, 9) and the electric cables (10). A pneumatic jack (16) rotates a ratchet wheel (12) which in turn actuates the spring loaded plunger (17) which operates the limit switches (20). In the event of any failure of the mechanism the defective arm can be detached from the support bracket (3) and repaired without interfering with the flow of articles in the other parallel streams.

Patent DE-2756392-A1 (DE)
Title: Dry transfer process for marks - using adhesives contg. sticky polymers and polar waxes
Inventor: SHADBOLT PHILIP
IPC: B44C1/17
Filed: 1977-12-17
Abstract: Dry transfers comprise a flexible, transparent or translucent support sheet, several transferable marks applied onto the support sheet and a coating of an adhesive substance over the marks and projecting over the surface of the surface of the support sheet. The adhesive coating contains adhesive components for dry transfer and a decoatable wax contg. polar radicals. The concn. of wax is such that when the adhesive compsn. is deposited from a soln. or dispersion in at least one organic solvent and the adhesive is duel by evaporation, there is an interaction between the adhesive and the marks. This results in the adhesiveness of the adhesive above the marks being greater than the adhesiveness of the adhesive on the support sheet between the marks. The risk of the adhesive of the sheet removing a mark already transferred onto the receptive surface if reduced. The adhesiveness of the sheet is reduced, thus facilitating the manipulation of the sheet.

Title: Plastics replaceable cap for telephone mouthpiece - damps undesired resonance by hole patterns in cap and cover
Inventor: SCHEELE EDMUND
IPC: H04R1/12
Filed: 1978-05-31
Abstract: In a telephone microphone capsule containing a transistor amplifier (13), sound pressure on the membrance (3) causes the coil (1) to move accordingly in the field of a magnet (2). A replaceable plastic cap (8) protects the mouthpiece cover (11) on grounds of hygiene. Both of these have holes (9, 14, u0) through which sound waves pass to the membrane. An undersired resonance in the 2 to 3 khz range, resulting from esp. the air enclosed between the cap (8) and cover (11) is damped by arranging that the holes (9, 14, 10) be similar in size and disposed on three concentric circles.

Title: Generation of structures on semiconductor surfaces - by producing charge mask on insulating surface which is then simultaneously irradiated by wide electron or ion beam
Inventor: DITTMAR WERNER DR ING
IPC: H01L21/033
Filed: 1978-10-09
Abstract: A charge mask is produced on an insulating surface or ions are implanted in the semiconductor element. A charge mask is produced once by a focussed electron beam on an insulating layer. It is used for production of structures on the semiconductor surface by so irradiating the semiconductor surface by a widely spread electron or ion beam, that all points of the semiconductor platelet to be irradiated are simultaneously hit by the electron or ion beam. An electron source (6) generating a writing beam (8) is mounted on the symmetrical axis (7) of a semiconductor chip (9). The beam is focussed by an electrical or magnetic focussing system (10). The programmed control computer (12) switches the beam (8) on and off by means of control pulses conducted by a lead (13). One pair of deflection plates (14) is installed perpendicularly to the writing plane while another pair (15) is installed in parallel to it.
